How does convection cause ocean currents?

• During the process of convection, energy is transferred to the atmosphere, forming winds. These winds power surface currents.

• During the process of convection, the heating of surface water by the sun results in upwelling.

• During the process of convection, energy in warm water is lost to its surroundings. The water cools, becomes denser, and sinks.

• During the process of convection, more minerals and gases dissolve in warm water. This increases the density of the warm water and causes it to sink.
